This paper discusses the application of a new two-dimen sional algebraic integer encoding scheme for the design of a cost-effective DCT (Discrete Cosine Transform) processor for the JPEG and MPEG applications. The paper concen trates on the efficient implementation of the 2D algebraic integer DCT. The processor takes advantage of the low complexity, multiplierless, high-precision nature of the alge braic integer encoding scheme. Details are provided for the DCT processor including a description of a CMOS test chip recently submitted for fabrication.
